<p>Vous connaissez sans doute <a href="https://jupyter.org/">Jupyter</a>, cet outil de développement tournant dans un navigateur qui est particulièrement en vogue chez les scientifiques et plus généralement dans les domaines liés au traitement des données. Aujourdʼhui je vais te parler d’une possibilité offerte par Jupyter qu’il ne me semble pas, sauf erreur de ma part, avoir vu évoquée ici, à savoir le développement dʼapplications web.</p>

<h1 id="à-propos-de-jupyter">À propos de Jupyter</h1>
|
|||
|
|
<p>À titre personnel, et peut-être comme beaucoup des plus anciens (disons 40 ans et plus), j’ai longtemps été très réticent à ce « machin à la mode » ne voyant pas bien ce qu’il pouvait apporter à mon flux de travail habituel basé sur un éditeur de texte et une console, et aussi ne lui trouvais-je que des inconvénients :</p>
|
|||
|
|
|
|||
|
|
<ul>
|
|||
|
|
<li>lancer <code class="language-plaintext highlighter-rouge">jupyter-notebook</code> dans une console, basculer sur le navigateur, parcourir l’arborescence, juste pour pouvoir visualiser un fichier ipynb me semble très peu ergonomique. Nous sommes en 2019 et ce truc ne gère pas le double clic. Il y a des solutions pour contourner ce problème, par exemple <a href="https://nteract.io/desktop">nteract</a> est une application de bureau basée sur electron qui permet de se passer du navigateur ;</li>
|
|||
|
|
<li>le fait que les cellules de code puissent être exécutées dans n’importe quel ordre peut amener à des confusions à la lecture des notebooks ;</li>

<li>le format ipynb (qui est en fait du json contenant plus d’informations que le simple code) est nativement peu compatible avec git : par exemple le simple fait d’exécuter une cellule modifie la numérotation de celle-ci et git détecte une modification, là encore, <a href="https://nextjournal.com/schmudde/how-to-version-control-jupyter">il y a des solutions pour contourner ça</a>, mais tout de même ;</li>

<p>Eh bien, j’avais tort.</p>

<p>En effet, Jupyter ne vise pas à remplacer notre bonne vieille console, et encore moins notre éditeur de texte favori, mais se place entre les deux. Je paraphraserai <a href="https://linuxfr.org/news/python-pour-les-sciences-une-presentation">la dépêche Python pour les sciences</a> en disant que Jupyter est <em>une console sous stéroïdes</em>. En effet, Jupyter permet d’exécuter des blocs de code sans avoir à écrire / sauvegarder / exécuter un script en bonne et due forme et, à l’instar de la console <a href="https://ipython.org/">iPython</a> dont <a href="https://linuxfr.org/news/sortie-de-ipython-jupyter-notebook-4-1">Jupyter dérive directement</a>, tous les objets sont sauvegardés dans un noyau pour pouvoir être réutilisés ailleurs dans le programme sans avoir à tout ré-exécuter. Ceci en fait un excellent outil d’expérimentation et de prototypage de programmes.</p>
|
|||
|
|
|
|||
|
|
<p>Par ailleurs, le fait que les notebooks Jupyter contiennent non seulement le code, mais aussi les graphiques et figures produits, et qu’il soit possible d’y adjoindre du texte enrichi (Markdown, HTML, LaTeX…) les rendent particulièrement intéressants pour l’enseignement et le partage des connaissances (et non pas le partage du code, car comme dit précédemment et <a href="https://linuxfr.org/nodes/115554/comments/1763182">comme le font remarquer certains à juste titre</a>, le code est fortement obscurci par le format ipynb).</p>
|
|||
|
|
|
|||
|
|
<p>Il est intéressant de noter que Jupyter est régulièrement évoqué au sein du mouvement <em>open science</em>, mouvement qui vise à faciliter la diffusion au sein de la communauté scientifique et auprès du grand public, non seulement des résultats et connaissances scientifiques, mais aussi des données brutes et des protocoles d’analyses et de traitements de ces données. Voir par exemple ces quelques liens: <a href="https://reproducible-analysis-workshop.readthedocs.io/en/latest/index.html">[1]</a> <a href="https://arxiv.org/ftp/arxiv/papers/1804/1804.05492.pdf">[2]</a> <a href="https://www.linuxjournal.com/content/jupyter-future-open-science">[3]</a>.</p>

<p>Bien évidemment ces notebooks Jupyter sont exportables dans différents types de formats (HTML, PDF, etc.) et peuvent également être aisément mis en ligne. <a href="https://nbviewer.jupyter.org/">Nbviewer</a> permet, par exemple, de partager des notebooks simplement en passant une URL ou l’adresse d’un dépôt git.</p>
|
|||
|
|
|
|||
|
|
<p>Pour modérer cet enthousiasme débordant il est, premièrement, bon de rappeler que toutes ces visualisations (y compris sur nbviewer) sont strictement statiques. Il n’est pas possible d’interagir avec celles-ci et donc de ré-exécuter tout ou partie du notebook. Deuxièmement, c’est bien joli de partager des notebooks, mais quid des lecteurs qui ne maîtrisent pas bien, voire pas du tout, le langage dans lequel lesdits notebooks ont été développés ? Ce sont ces points que je me propose d’aborder ici.</p>

<p><a href="https://github.com/jupyter-widgets/ipywidgets">Ipywidgets</a> désigne un ensemble de composants graphiques pour le langage python (slider, combo box, boutons, etc.) destinés à rendre les notebooks plus interactifs. En gros il s’agit d’une architecture permettant de lier un objet python (le widget), tournant dans le noyau, à sa représentation JavaScript/HTML/CSS tournant dans le navigateur. Par exemple, afficher un slider qui permet de modifier la variable d’entrée d’une fonction et d’en afficher le résultat s’écrit simplement :</p>

<p>La fonction <code class="language-plaintext highlighter-rouge">interact</code> est, en fait, un raccourci vers un ensemble de widgets graphiques avec des choix faits par défaut selon le type d’objet (int, float, bool, list, etc.) passé à la fonction f. Il est possible d’avoir un contrôle beaucoup plus fin en paramétrant le widget à la main. Le code ci-dessous donne strictement le même résultat :</p>

<p>C’est, évidemment, beaucoup plus lourd, mais il me semble que cet exemple illustre bien la richesse des potentialités offertes par ipywidgets. <a href="https://ipywidgets.readthedocs.io/en/latest/index.html">La documentation de ipywidgets</a> est tout simplement excellente, et il est possible de maîtriser cette bibliothèque assez rapidement.</p>
|
|||
|
|
|
|||
|
|
<p>Ipywidgets n’est pas seulement une bibliothèque d’objets graphiques. Il s’agit véritablement d’un cadre de développement sur lequel les développeurs peuvent s’appuyer pour écrire leurs propres bibliothèques de widgets. En voici quelques-unes :</p>
|
|||
|
|
|
|||
|
|
<ul>
|
|||
|
|
<li><a href="https://github.com/mariobuikhuizen/ipyvuetify">ipyvuetify</a>, pour celles et ceux qui trouveraient les widgets de base d’ipywidget trop austères, cette bibliothèque apporte à Jupyter les widgets <a href="https://vuetifyjs.com">vuetify</a> qui implémentent des composants graphiques obéissants aux spécifications de <em>material design</em> ;</li>
|
|||
|
|
<li><a href="https://github.com/bloomberg/bqplot">bqplot</a>, un « doit-avoir » absolu pour quiconque s’intéresse à la visualisation en 2D de données. Je donnerai un exemple d’implémentation ci-dessous, mais, en bref, dans bqplot chaque élément d’un graphique (axes, légende, données, graduations, etc.) est en fait un widget avec lequel il est possible d’interagir et de modifier les propriétés programmatiquement ;</li>
|
|||
|
|
<li><a href="https://github.com/maartenbreddels/ipyvolume">ipyvolume</a>, même chose mais pour la visualisation de données en 3D, en s’appuyant sur WebGL ;</li>
|
|||
|
|
<li><a href="https://github.com/jupyter-widgets/ipyleaflet">ipyleaflet</a>, affichage et manipulation de cartes et données géographiques ;</li>
|
|||
|
|
<li><a href="https://github.com/maartenbreddels/ipywebrtc">ipywebrtc</a>, permet de diffuser et manipuler du contenu audio ou vidéo depuis à peu près n’importe quelle source (fichier, webcam, etc.).</li>
|
|||
|
|
</ul>
|
|||
|
|
|
|||
|
|
<p>Afin d’illustrer la compatibilité entre ipywidgets et d’autres bibliothèques (ici bqplot) le code ci-dessous permet d’effectuer les actions suivantes :</p>
|
|||
|
|
|
|||
|
|
<ol>
|
|||
|
|
<li>sélectionner une fonction à tracer via un menu déroulant ;</li>
|
|||
|
|
<li>la figure est mise à jour en fonction du choix (ipywidgets -> bqplot) ;</li>
|
|||
|
|
<li>il est possible de déplacer des points dans la figure ;</li>
|
|||
|
|
<li>les coordonnées des points sont affichées dans un champ texte (bqplot -> ipywidgets).</li>

<p>Toutes ces bibliothèques sont relativement jeunes et il peut arriver que la documentation ne soit pas exhaustive (c’est, par exemple, le cas pour bqplot). Dans ce cas, il peut être très intéressant de cloner ou télécharger le dépôt Github et d’aller fouiller dans le répertoire <em>examples</em>. Dans le cas de bqplot, c’est une véritable mine d’or.</p>

<p>Maintenant que nous savons comment créer une petite interface graphique, pourquoi ne pas cacher tout ce code afin de ne pas effrayer les débutants ? <a href="https://github.com/oschuett/appmode">Appmode</a> est une extension pour Jupyter qui permet très exactement de faire cela : l’extension ajoute un bouton <code class="language-plaintext highlighter-rouge">Appmode</code> à l’interface de Jupyter qui permet de créer une nouvelle instance du notebook, celui-ci est alors entièrement exécuté et seules les widgets sont affichées.</p>
|
|||
|
|
|
|||
|
|
<p>Si elle est très efficace, cette extension peut être problématique si le notebook est destiné à être hébergé sur un serveur Jupyter ouvert fournit pas votre entreprise / université / école… En effet le notebook reste entièrement accessible et rien n’interdit l’exécution de code arbitraire. C’est ce problème que solutionne <a href="https://github.com/voila-dashboards/voila">voilà</a>. Ce projet est très jeune puisqu’il n’a été annoncé que cet été dans <a href="https://blog.jupyter.org/and-voil%C3%A0-f6a2c08a4a93">ce très instructif billet de blog</a> mais il s’avère déjà particulièrement efficace. En bref, lorsque l’URL du notebook est appelée, celui-ci s’exécute intégralement et les cellules de résultats (incluant les widgets) sont converties en une page HTML + JavaScript qui est ensuite présentée à l’utilisateur. En principe, il (ou elle) ne peut plus exécuter de code arbitraire. Pour celles et ceux à qui ça parle (dont je ne fais pas partie), ça repose, entre autres, sur <a href="https://www.tornadoweb.org/">tornado</a>.</p>

<p>La <a href="https://voila-gallery.org/services/gallery/">galerie</a> de <em>voilà</em> regorge d’exemples, comme <a href="https://voila-gallery.org/user/voila-gallery-gaussian-density-nzh9rp3d/voila/render/index.ipynb?token=zu-axkwTRI2Fr-QOaNHPGw">celui-ci où on peut jouer avec une fonction gaussienne</a>. En voyant cet exemple il est utile de rappeler que tout ceci n’est rien d’autre qu’un notebook Jupyter.</p>

<p>Dernière étape pour finaliser notre application web : la mise en ligne. Comme je l’évoquais plus haut, <em>nbviewer</em> est exclu puisque celui-ci ne permet pas d’interagir avec les notebooks. Si vous avez la chance d’avoir votre propre serveur Jupyter distant (ou d’avoir des administrateurs et des administratrices compétents et sympas), c’est immédiat. Il vous suffit d’activer l’extension <em>voilà</em> : <code class="language-plaintext highlighter-rouge">jupyter serverextension enable voila --sys-prefix</code> puis de préfixer l’URL du notebook avec « voila » :
|
|||
|
|
<code class="language-plaintext highlighter-rouge">http://URL_DU_SERVEUR/NOM_DU_NOTEBOOK.ipynb</code>
|
|||
|
|
devient
|
|||
|
|
<code class="language-plaintext highlighter-rouge">http://URL_DU_SERVEUR/voila/NOM_DU_NOTEBOOK.ipynb</code></p>
|
|||
|
|
|
|||
|
|
<p>Notez qu’il est possible de visualiser le rendu du notebook en local, entrez <code class="language-plaintext highlighter-rouge">voila notebook.ipynb</code> dans votre terminal et le rendu sera visible sur <code class="language-plaintext highlighter-rouge">localhost:8866</code>.</p>
|
|||
|
|
|
|||
|
|
<p>Si vous n’avez pas de serveur Jupyter ouvert sur le web, tout n’est pas perdu. <a href="https://mybinder.org/">Mybinder</a> permet de venir se brancher sur un dépôt git, puis, à l’aide d’un fichier <code class="language-plaintext highlighter-rouge">requirements.txt</code> ou <code class="language-plaintext highlighter-rouge">environment.yml</code> listant les dépendances requises, Mybinder va construire une image Docker du dépôt et votre notebook sera servi via un <a href="https://jupyterhub.readthedocs.io/en/latest/">JupyterHub</a>. Le contenu du fichier <code class="language-plaintext highlighter-rouge">environment.yml</code> pour les exemples précédents est :</p>
|
|||
|
|
|
|||
|
|
<div class="language-yaml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="na">channels</span><span class="pi">:</span>
|
|||
|
|
<span class="pi">-</span> <span class="s">conda-forge</span>
|
|||
|
|
<span class="na">dependencies</span><span class="pi">:</span>
|
|||
|
|
<span class="pi">-</span> <span class="s">numpy</span>
|
|||
|
|
<span class="pi">-</span> <span class="s">ipywidgets</span>
|
|||
|
|
<span class="pi">-</span> <span class="s">bqplot</span>
|
|||
|
|
<span class="pi">-</span> <span class="s">voila</span>
|
|||
|
|
</code></pre></div></div>
|
|||
|
|
|
|||
|
|
<p>Finalement le notebook est accessible par un lien de la forme : <a href="https://mybinder.org/v2/gh/aboulle/Divers/master?filepath=%2Fipywidgets_linuxfr.ipynb"><img src="https://mybinder.org/badge_logo.svg" alt="Binder" /></a>
|
|||
|
|
Deux remarques utiles à ce stade :</p>
|
|||
|
|
|
|||
|
|
<ol>
|
|||
|
|
<li>la création de l’image Docker peut prendre plusieurs minutes ;</li>
|
|||
|
|
<li>concernant <em>voilà</em>, il existe apparemment un moyen d’atterrir directement sur le rendu HTML du notebook et non le notebook lui-même en préfixant le nom du notebook avec <code class="language-plaintext highlighter-rouge">/voila/render/</code>, mais pour moi cela ne semble pas fonctionner avant la première création de l’image. Il faut donc cliquer sur le bouton ‘voilà’ dans le notebook pour cacher le code source.</li>
|
|||
|
|
</ol>
|
|||
|
|
|
|||
|
|
<p><a href="https://www.heroku.com/">Heroku</a> est une solution alternative à mybinder. La procédure de déploiement est cependant moins aisée (mais les tutoriels sont très bons), et <a href="https://devcenter.heroku.com/articles/python-pip#scientific-python-users">les dépendances considérées comme « obscures » par heroku</a> ne sont pas gérées : par exemple SciPy n’est pas géré, ce qui est handicapant pour des applications techniques ou scientifiques.</p>
|
|||

|
<h1 id="mot-de-la-fin">Mot de la fin</h1>
|
|||
|
|
<p>Pour conclure, et pour illustrer le fait qu’il est possible de créer des applications relativement élaborées, je partage ici un lien vers une application scientifique que j’ai récemment développée et qu’un collègue de notre département TIC a œuvré à <a href="https://radmax.unilim.fr">mettre en ligne</a> (un grand merci à lui !).</p>
|
|||
|
|
|
|||
|
|
<p>En bref il s’agit, dans le graphique de droite, de faire coller la courbe calculée (en rouge) sur des mesures de <a href="https://fr.wikipedia.org/wiki/Cristallographie_aux_rayons_X">diffraction des rayons X</a> expérimentales. Les graphes de gauche sont manipulables et le rendu des calculs est donné en temps réel dans le graphe de droite. Pour le contexte, l’objectif final est de déterminer les dommages que subissent des matériaux soumis à des radiations. Ces dommages sont quantifiés par l’évolution en profondeur du taux de déformation et de désordre atomique (graphes de gauche). Le calcul est paramétré par les différents widgets. C’est encore expérimental, la stabilité n’est donc pas garantie ; de plus, il est possible que l’URL change dans les jours à venir.</p>
